High End
The high-end range includes the gearbox lines GSA, GSB, GSF (inline), GSD (flange gear) and GSBL (angle gear). All lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings. The housings are designed from a one-piece, robust housing. This improves the gear rigidity and enables the absorption of higher loads. The sun pinions are fitted with an additional bearing system in order to ensure quieter operating behavior. The 2-stage versions are constructed in a space-optimized design. Due to the lower torque values, the input stage is dimensionally smaller than the output stage.
GSA
- Low backlash for highest precision, standard as low as <=3 arcmin, optional as low as <= 1arcmin
- High radial and axial forces permissible
- Simple mounting without intermediate flange
GSB
- Low backlash for high precision, standard up to <=3 arcmin, optional up to <= 1arcmin
- High torque level
- Best corrosion protection for complete housing including output side
GSF
- High load level due to double bearings
- High torsional rigidity
- Optimum protection against dust particles and water jets
High End Economy
The high-end economy lines GSN and GFE are equipped with ground, helical-cut precision components, which ensure low operating noise, very quiet operating characteristics and above-average torque absorption. Both lines have a full needle bearing, which has been especially designed for high torques. The planetary carriers are manufactured as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash.
